Dee spends $0.25, $0.30, $0.10 and $0.04.
How much $ does she spend in all?
Answers
By adding all the money she spend we get $0.69
What is the unitary method?
The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Dee spends $0.25, $0.30, $0.10 and $0.04.
We need to find the money she spend in all.
Therefore, we have to add all the expenditure
0.25 + 0.30 + 0.10 + 0.04 = 0.69
The total money she spend could be 0.69.

bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.

Answer:
3. a =42
Step-by-step explanation:
2 ways you can go about this, you can either multiply 7x6 to get 42 as your answer. Or you can go through the options and divide each by 6 until eventually you'll find the one option that equals 7 which you would find is choice 3 a = 42

You can evaluate -6(4 2/3) as -28.
To evaluate the expression -6(4 2/3), you can use either of the following methods:
Method 1: Convert the mixed number to an improper fraction and then multiply.
First, convert the mixed number 4 2/3 to an improper fraction:
4 2/3 = (4 * 3 + 2)/3 = (12 + 2)/3 = 14/3
Now, multiply -6 by 14/3:
-6 * (14/3) = (-6/1) * (14/3)
Now, multiply the numerators and denominators separately:
= (-6 * 14) / (1 * 3)
= -84/3
Finally, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (which is 3):
= (-84/3) ÷ (3/3)
= -28
So, -6(4 2/3) = -28.
Method 2: Distribute the -6 to both parts of the mixed number.
-6 * 4 = -24
-6 * (2/3) = -4
Now, add the results together:
-24 - 4 = -28
So, using either method, you can evaluate -6(4 2/3) as -28.

To determine the coordinates of the points that satisfy the condition of being 10 units from (1,8) on the x-axis, we can set up two equations based on the distance formula.
Let's assume the coordinates of the points are (x, 0), where y = 0 represents the x-axis.
Using the distance formula, we have:
√[(x - 1)^2 + (0 - 8)^2] = 10
Simplifying the equation, we get:
√[(x - 1)^2 + 64] = 10
Squaring both sides, we have:
(x - 1)^2 + 64 = 100
Now, you can solve this equation to find the possible x-coordinates of the points.
Based on what you just explained about determining the coordinates of points that satisfy a given condition, let's move on to a related concept
